Assessment
The Seat Leon 1.6 TDI 90hp is a 1.6L turbocharged diesel engine producing 90 BHP and 230 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 140 BHP and 310 Nm — a gain of around 50 BHP (56%) and 80 Nm (35%).
This engine scores highly for remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
Considerations: Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.
Fuel economy note: economy gains unlikely at full power; depends on driving style.
All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
